Ability to get occurred exception - Issue 1592

[PatilShreyas]

As issue #1592,
I have updated code as FirebaseRecyclerPagingAdapter and added an ability to get the occurred Exception while using FirestorePagingAdapter.

To use this, the user can Override onError() method of Adapter class.

e.g.

 @Override
 protected void onError(@NonNull Exception e) {
          mSwipeRefreshLayout.setRefreshing(false);
          Log.e(TAG, e.getMessage(), e);
 }
